Convergence sublayer for use in a wireless broadcasting system

摘要

A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

1. A method of encapsulating data, the method comprising:
receiving a content stream of data packets that are formatted in accordance with a first protocol; receiving, from a lower layer, information identifying a container size established for the content stream, the container size being different from a container size established for at least one other content stream; fragmenting and packing the data packets that are formatted in accordance with the first protocol to form data units formatted in accordance with a second protocol, the data units being sized based on the container size; encapsulating the data units that are formatted in accordance with the second protocol to form second protocol data packets; and providing the second protocol data packets to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.
